Game Won't Launch

[mrm215]

I installed Sims 2 Ultimate Collection two months ago and it worked fine up until this week. Now it won't launch from origin or from my computer shortcut. I tried the "repair" option under the right click menu. I also un-installed my anti-virus software and tried to launch origin as an administrator as per instructions on origin's "help" page. Nothing's working, any suggestions outside of completely reinstalling origin/game?
